If it goes up (even slightly) and you don't crash or green/blue screen and there's no graphical anomalies on the screen during the bench, then bump it an additional 25mhz. Keep doing this until either the graphics score starts to drop, you crash, or you have graphical artifacts, and then drop the core clock by 12mhz and test again. If it's stable there, bump it up 6mhz and try again. If it's stable there then just stay there for now. Then you'd repeat the same on the memory (though i'd start with increments of 50mhz, then 25, then 12, etc) until it's stable. Once you think you have a stable max-OC then you should try some other benchmarks and games and see if you crash or have artifacts. If you do then you will need to start bumping things down until you become stable again. Once you're there, you could take a more advanced step that usually isn't worth doing if you don't care about truly maxing your overclock, and try dropping your core clock and bumping your memory a little bit to see if that increases your performance, if it does, keep going until you reach instability and then back off a bit.
